Hello Gang,

One of the postdocs here found an ad for Streck's  S.T.F. fixative. 
She would like to know if any of you have tried it, and what do you 
think of it?

It's promoted for use with ISH applications, yet is not a 
crosslinker.  It's my understanding that denaturing fixatives are not 
good for ISH.  So what do you suppose this stuff is?  Is zinc 
considered a noncrosslinker (it doesn't form covalent bonds, but 
rather joins through metallic complexation bonds)?

Curious in Oregon
